In defense of zoos

I just signed up to, once again, volunteer at the National Zoo -- this time in the Bird House.  Unlike 20 years ago, when I attended some exhibit-specific training and learned from the keepers, volunteering at the zoo now involves background checks and shots!  But I'm finished with the prelims and looking forward to starting my try-out period!  Since I've been thinking a lot about zoos lately, I thought I'd re-post about zoos:

An article in Conservation Magazine reported on research that suggests that, while zoos play an important role in conservation and species protection, they might want to try to better coordinate their efforts – more bang for the buck.  This report made me think about why it is I still love zoos.  Here’s an earlier post on the topic:
I’ve often heard people say, “I hate going to zoos.  It’s so cruel to keep the animals in cages.”  Recently, there have been news stories regarding the mistreatment of crocodiles by zoogoers in China.  Since I love going to the zoo, these statements and news storiesDSC_0144trouble me, and I rethink whether zoos should exist in our modern world.  Truth be told, I’d prefer to see zoos that don’t concentrate heavily on the “charismatic megafauna” – lions and tigers and bears, oh my!  I’d rather see animals like invertebrates, Amazonian exhibits where we work to see the sloth in a tree, or birds flying freely in large enclosures.  But let’s be honest, most folks won’t visit the zoo unless they can see an elephant or a tiger or a panda.  Despite this difference of opinion on the ideal fauna for a zoo, I believe that, when the animals are treated in humane conditions, zoos do indeed have an important role to play in today’s society.  Here’s why:
  • I’ve never seen one of those!  Most of us will not be able to travel to the Galapagos or Kenya to encounter wildlife in its native habitat.  Zoos are often the only place where people can encounter and appreciate animals other than pets and farm animals.  Schools often do not allow animals in the building and field trips to observe local wildlife are pretty much non-existent.  As Richard Louv states in his book, Last Child in the Woods, “In the patent-or-perish environment of higher education, we see the death of natural history as the more hands-on disciplines, such as zoology, give way to more theoretical and remunerative microbiology and genetic engineering.”  The zoo is one of the last homes of environmental and zoological education.  At the zoo we can hear a lion’s roar, feel a sea urchin in the invertebrate house touch tank, smell the musky smell of the maned wolf during breeding season, and even be splashed as the seals and sea lions dive into cold water.
  • What?  I can help out?  Zoos are a great volunteer opportunity for people interested in learning more than can be taught in a short weekend visit.  I was a volunteer at the Smithsonian National Zoo for over 5 years, first atbeautiful swimmer the Invertebrate House and then at the Conservation Research Center in Front Royal.  What a great experience!  Under the guidance of expert zookeepers and curators, I learned about animals as varied as the octopus, the hissing cockroach, the Przewalski horse, and the leaf-cutter ant.  I helped feed many of the animals, cleaned their tanks and enclosures, taught zoo visitors about the animals, mourned the loss of old animal friends, and celebrated new births at the zoo.  For an aspiring Dr. Doolittle, it just doesn’t get any better than that!
  • The modern ark.  Zoos serve as a last preserve for animals that have either disappeared in the wild or are in danger of going extinct.  Zoos host breeding programs for many of the world’s most endangered species.  The Smithsonian National Zoo sponsors breeding programs for the Guam rail, scimitar-horned oryx, black-footed ferret, maned wolf, and the Panamanian golden frog, just to name a few.  Scientists and students from around the world come to study the latest captive breeding techniques, as well as field biology methods for surveying animals in the wild. 
Many, although not all, of today’s zoo animals were born and bred in captivity, or cannot be returned to the wild because of injury.  When a zoo is well-maintained (see accreditation by the Association of Zoos and Aquariums) and animals live in stimulating, enriching environments, I believe zoos have much to offer.  Why not visit and support your local zoo this weekend?

Mammal Monday -- pygmy hippos!

This week I'm reposting about an endangered mammal:  pygmy hippopotamus (Choeropsis liberiensis), which is listed as endangered on the IUCN red list.  Only a hippo could be considered the “pygmy” of its species at 350-600 lbs!  This shy, solitary, nocturnal animal is found in western Africa, where it lives in forests near streams.  Similar to the larger hippo, pygmy hippos can shut their eyes and ears underwater, but their feet are not as webbed as their larger cousins.  The pygmy hippo is a vegetarian that has a stomach with four chambers to help break down cellulose found in the plants it eats.  Here’s an interesting factoid:  the pygmy hippo wanders through its range, following well-defined trails, spreading its feces by spinning its tail while defecating.  Hippos even have hairs with split ends on their tails to assure maximum “fling” of its feces!  Pygmy hippos reach sexual maturity at around 4 to 5 years of age, and gestation lasts about 6 months. The young cannot walk at first, so the mother hides the young in streamside vegetation while she feeds. 

The major threat to pygmy hippos is habitat loss due to logging, farming, and other human development, as well as political instability in the region.  This fact answers the question, “Why should we care if pygmy hippos are endangered?”  Because if they’re declining because of loss of forests and streams, that means every animal, including humans, that depends on forests and streams is also impacted.  Forest habitats help to store and clean water, as well as provide homes for many species in the local food chain. 

See a baby pygmy hippo take her first swim!

Why not quesadillas?

Proof positive -- I am not a "food stylist."  But this photo is meant to remind you that meat-free Friday can also be "fast and easy Friday"!  Quesadillas are a great go-to on a busy Friday night.  All you need are tortillas, cheese, and veggies of your choice.  At our house, we go with onions, red and green peppers, and tomatoes, but you can add whatever you like -- even a little chopped spinach!  Add a little guacamole and sour cream, fill in with some refried beans (vegetarian of course), and you've got a delicious and quick meat-free Friday meal!

International Polar Bear Day!

It seems I was a bit early with my polar bear post this month, and now I'm a day late wishing you a wonderful International Polar Bear Day (it was yesterday), sponsored by Polar Bears International.  No worries!  We can celebrate polar bears every day!  Step 1:  Work to limit climate change through individual, local, and global action.  Step 2:  Take a moment to enjoy polar bears:

Mammal Monday -- Chipmunks!


I don't think I've ever visited a place in the U.S. where I didn't see chipmunks (I found the little guy above in Bryce Canyon Utah).  That's probably because there are 25 species of chipmunks and only one of those species is found outside of North America (the Siberian chipmunk, but it's not just found in Siberia...)  Unlike their grey squirrel cousins, chipmunks are ground-dwelling squirrels that live in burrows.  We're not seeing many chipmunks this time of year, but come spring they'll be active again, collecting food and getting ready for mating season in late spring and fall.  They're omnivores and "crepuscular," which means they're most active at dusk and dawn. 

I've noticed that chipmunks make little sounds whenever I see them, so I did a little checking.  It seems that, like birds, they use different vocalizations at different times.  Check out this research:

This one's a winner!




I love this meat-free Friday recipe, because it's easy and tasty!  It comes from one of my favorite cookbooks, A Beautiful Bowl of Soup by Paulette Mitchell.  If you don't have this cookbook yet, it's time to make an order.

Asian Noodle Soup

Ingredients

  • 8 cups vegetable stock
  • 1/4 cup soy sauce
  • dash of pepper to taste (for extra zip, toss in some red pepper flakes)
  • 4 oz. dried thin Chinese wheat-flour noodles
  • 8 cups fresh spinach, coarsely chopped
  • 2 cups corn kernels
  • 2 green onions, chopped
Instructions
  1. Combine and heat the vegetable stock, soy sauce, and pepper.  Bring to a boil.
  2. Add the noodles, spinach, corn, and green onions.  Cook until spinach is wilted and noodles are tender.
  3. Serve in bowls.  First put the noodles in the bowls and then add liquid.
Enjoy!
